I've moved my subwoofer from where it used to be in my room to a different place and it now sounds awful. So I need to move it again, not unexpected. I'm looking at my options.

I noticed that it would probably fit in the empty cupboard space under my gun cabinet. I know that subwoofer sound can be kind of weird. What happens to the sound if it is contained in a box with the doors closed? Low Hz sound penetrates better than hi Hz sound. What about if the front doors are opened? Would it become as directional as I would think or something different?
I'm just asking, I don't plan to try it.

My 1st thought is, your sub's enclosure will fit in your "Cupboard"?
2nd is, IF it does and sounds good there, you could remove the door(s) and just fashion your own false front/grille and cover the opening, so its hidden, but yet acoustically transparent.
I did something similar years ago with a custom entertainment center I built, with a built in Center Channel.  I designed with Kicker Speakers and a homemade Cross over...

But to your issue.  
Subs are generally thought of as semi-omni directional, whereas the higher frequency drivers like Tweets and mids, they are definitely way more directional. BUT, there is still some directionality and a clear path from the driver to the listener position is preferred.

You'll have to just move it around a few times and see how it sounds.
I find subs usually sound best a foot or so from each wall in a corner, but they can't always go there, so you just have to experiment. Plus, everyone has different tastes in SQ.

I'm having or going to have this problem putting together a budget theater in our living room that is not only, not 100 % rectangle, has too much furniture, too many doors and too many windows for the opportune home theater setup.

Things to try to make it sound better:

-insulate the feet with dampening material
-spike feet to couple with the floor
-move closer to corner
-move farther from corner
-move off center line in all dimensions of the room
-turn down the power/amplification
-adjust the cutoff frequency, usually lower frequency to start
-remove acoustically disruptive objects away from the sub
-rotate if forward firing
-add weight to the top (bricks or books)

You are going to trade "sounds bad" for "sounds bad and causes rattles" by putting it in a cupboard.

I never even thought of the rattling. Everything would vibrate as the sound waves tried to get out of the container. Beyond that I would think that it would be like putting a sound muffler all around the sub. I guess the wood would act like a sound absorbing material. And if the doors were open the bulk of the sound would go straight out of the opening. But again, I know low sound waves can do stuff that is not expected.

Install the SVS Soundpath sub isolation system.  They do exactly that.

I was getting some rattling/rumbling on big bass hits even with a very good sub until I added these.

This may help getting good bass sound - it's called a sub crawl.

Put your sub in your seat, turn on, walk around the room until you find the spot where it sounds best. That's your new location to put the sub.
As others said, avoid putting inside something.

In my experience, bad sub integration is more often than not simply related to the crossover point set too high or gain set too high. Play with that first.

Next, try to tune the sub for the new location. It's probably generating new room resonances, so there may be new bump or cancellation where one didn't exist before. It may now be out of phase with your mains. Re-set the phase if you can (turn up the crossover point on the sub, play with the phase until you find the point where tones at the crossover point are loudest (i.e., the sub and mains are in phase), then dial back the crossover point/gain a bit until the crossover point is smooth again. If your sub has a parametric EQ, you can then attack  the resonance/cancellation points.

If that doesn't work, you may need to relocate the sub.

If it has to go in the cupboard, you could always build a new set of doors with open centers covered with grill cloth.
